T 0 all whom it may concern:

Be it known that i, GEORGE A. Srnzesn, a citizen of the United States, residing at Cincinnati, in the county oi Hamilton and State of Ohio, have invented new and useiul Cistern-Cleaner, of which the i'i'illowing is a speciiication.

This invention relates to cistern clean rs.

The object of the invention is to simplify and in'iprove the construction oi such apparat-us, and with the minimum of labor, to in sure the removal of dirt and sediment from the bottom of a cistern wit'iout roiling the water therein and at the same time to aerate the water thereby to remove any foul gases contained therein.

i v ith the above and other objects in view, as will appear as the nature of the invention. is better understood, the same consists in he novel construction and combination of parts or" a cistern cleaner as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in side elevation of a cistern cleaner constructed in accordance with the present invention. Fig. 2 is a view in vertical longitudinal section through the cleaner. Fig. 3 is a perspective detail view of the cap plate 01'' the cleaner. Fig. 4 is a fragmentary detail view in section of a portion oi the apparatus.

Rcierring to the drawings, 1 designates the body 01' the apparatus, which is preferably quadrangular in cross section and is constructed of galvanized iron, the overlapped edges at the joint (not shown) being secured together either by solder, by rivets or by both, as may be preferred. The upper end of the body is closed by a cap plate 2 which is constructed preferably oi aluminum, and it is provided with a downturned flange 3 in which the upper end of the body fits, and is held therein by rivets 4.

The upper face of the cap plate is provided at each of its four corners with an angular flange 5, each of which is inset "from the adjacent edge ol the plate, and has its outer face beveled or inclined in order to permit proper attachment with a cap 6, preferably of copper, and which is assembled with the flanges by rivets 7. The lower edges of the cap are cut away, as shown at 8, in order to provide air escapes, as will presently appear.

Mounted upon the upper face of the plate I is the controlling valve which consists of a l curved arm 9 that 1S adapted to be close to the plate, and the outer extremity of which is designed to cover or uncover an escape opening 10 l'ormed in the plate, a guard or stop 11 covering the opening 10 serving to limit the rotation of the valve in one direction. The valve is held assembled with the plate by a screw 12 that is inserted irom the base late 16 arovided with le s 17 that are P l a oi suiiicient length to insure proper passage or" sediment or dirt within the body. T his base plate is connected with the bony by hinge, one leaf 18 of which is secured to the base and the other leaf 19 to a band 20 firmly riveted around the lower outside portion of he body. In order to hold the plate in closed position when the body is lifted, after the valve 9 has been operated, a spring catch isprovided, the upper end 21 of whichis riveted to the body and the lower end of which is provided with a spring too 22 to spring un der the lower side of the base plate.

The base plate is provided at its center with a quadrangular orifice against the wall of which is secured a resilient u standing packing 23 which is held in place yaquadrangular keeper 24, that is L-shaped in cross section and is secured to the base plate by rivets or bolts 25. The base plate will be constructed of aluminum the same as the top plate, on account of its lightness and nonoxidizable qualities. Of course, it is to be understood that the invention is not to be limited to the employment of this particular metal for these parts, as any other metal or substance adapted for the purpose may be substituted therefor. The opening in the base plate is normally sealed by a gravity valve 26 which is secured to the upper side of the base plate by a hinge 27.

All of the parts of the apparatus are constructed with a view to simplicity and durability and are designed to withstand rough usage without deterioration.

In the operation of the apparatus, the valves are closed and the body is forced to the bottom of the cistern b the pole, and as soon as the latter is turne to cause valve 9 Cir escapes from the body it passes upward through the water in the cistern and thereby aerates the same and removes therefrom any foul gases or odors that may be present.

What is claimed is 1. A cistern cleaner embodying a hollow body, and an upper and lower valve, the upper valve being rotatable about an longitudinal with that of the body, and corn stituting a means for positioning the body within and removing it from a cistern.

A cistern cleaner embodying a hollow body, cap and base plates secured thereto, a gravity valve carried by the base plate, and a rotary valve carried by the cap plate, and provided with means for attachment to a pole.

8. A cistern cleaner comprising a hollow body, cap and base plates secured thereto, a gravity valve carried by the base plate, a retary valve carried by the cap plate, and means connected with the latter valve to ef fect its rotation and to sink and raise the body.

4. A cistern cleaner comprising a hollow body, cap and base plates secured thereto, an

inward opening valve carried by the base plate, a rotary valve carried by the cap plate, and means connected with the valve to rotate the same and to lift and lower the body.

5. A cistern cleaner comprising a hollow body, a base plate hinged thereto, an inward opening gravity valve carried by the base plate, a cap plate rigid with the body and provided with anescape orifice, a guard dis posed over the orifice, a valve pivotally connected with the cap plate and rotatable about vertical axis to open or close the orilice, and a socket carried by the valve.

6. A cistern cleaner coin rising a hollow body, a base plate secured thereto and provided with a packing, an inward opening gravity valve carried by the base plate and arranged to engage the packing, a cap plate carried. by the upper end of the body and provided with flanges and with an orifice, a cap secured to the flanges and provided at their sides with cutaway portions, a'valve pivotally connected with the cap plate and rotatable about a vertical axis to open and close the orifice, a socket carried by the valve, and a pole having one end seated in the socket.

In testimony that I claim the foregoing as.
